CRYSTALYXÂ® STABLE-LYXÂ® is a very palatable supplement to be fed free-choice to all ages and types of equine. The formulation delivers supplemental energy, protein, macro minerals, trace minerals and vitamins in a highly palatable package and gives greater control of daily animal intake. Supplemental nutrients can improve growth rate, condition, lactation, health, appearance and all-around performance. Plus, STABLE-LYXÂ® contains AvailaÂ®-4 Amino Acid Complex and extra biotin for improved hoof growth and durability. Studies show brood mares cycle earlier and conception rates are higher when STABLE-LYXÂ® is provided before foaling. Do not feed STABLE-LYXÂ® to sheep or goats (this product contains copper).
